GUSTAV FRENKEL, OF COLOGNE, GERMANY PROCESS FOR MANUFACTURING BLOCKS OF LINOLEUM MATERIAL.

To allwhom it may concern:

Be it known that I, GUs'rAv FRENKEL, engineer, a subject ol' the German Emperor, re-

siding at Cologne on the Rhine, Rhenish l Prussia, Empire o fGermany, have invented a new and useful Process for Manufacturing Blocks of Linoleum Material, of which the A over upon itself in layers, and then pressing said layers to form a block, which is afterward cut by a suitable means.

ln the accompanying drawings, which show the mechanism employed in my process:l*`igure 1 is a longitudinal sectional view of the mechanism preferably employed in carrying out the process. Fig. 2 is a side elevation of the same. Fig. 3 is a detail view showing one hopper with its corresponding rolls. Eig. 4 is a detail view showing the several diii'erent colored strips and a single multicolored strip formed of the several single strips.

Similar reference numerals designate corresponding parts in all the figures of the draws. The mechanism preferably ,employed in forming the blocks comprises a suitable framework having arranged near the top a plurality of pairs of rolls 1 2, 3-4 5--6, 7-8 respectively, and above each pair of rolls is located a corresponding hopper 9--10-11-12 respectively. While only four pair of rolls are shown in the drawing, I

do not wish to limit myself to this number,

as more or less may be used without departing from the spirit of my invention. Located below the rolls and arranged substantially in the center of the frame is a single pair of rolls 22-23, the diameter thereof being preferably larger than the other rolls. The plurality of pairs of rolls are preferably mounted eccentrically, although they may be mounted concentrically if the rollers are made of vcertain shape. All of the rollers are provided with suitable operating gearing, which, through intermediate gearing, meshes with the gear of the drive shaft.

Specification of Letters Patent.

Application led June 12, 1907.

Patented April 27, 1909. serial No. 378,656.

Light and. dark material is alternately placed within the hoppers 9-10-11.-12 respectively, i. e. hopper 9 may contain light material, hopper .10 dark material, hopper 11 light material, hopper 12 dark material and so on, depending uponL the number of hop- .pers employed. This material is fed from each hopper through its respective pair of rolls, and because of the fact that the rolls are eccentrically mounted, strips 18-19- 20-21 of this material are formed, having alternate thin and thick portions 24 and 25 respectively,4 thus producing a correct grain effect. These strips, which are adapted to pass together, through the single pair of iolls 22-23, which are mounted concentric ally, are thus united to form a single strip of material having alternate layers of light and dark material. Just lprevious to entering between these rolls, the strips lie irregularly u on one another, and during the passage t rough the rolls, a miXing and equalizing action takes place, t'. e. particles of the material of the irregular strips are displaced as the excess linoleum material which is forced from the thicker places moves `toward the thinner places. lrlhe single strip thus pro duced, is folded in layers in a heated receptacle 28, which is preferably heated by steam. 'To fold this strip, in layers, an oscillating arm 27 is employed, whichisprovided at its lower end with two rollers 27, through which the strip is adapted to pass. This arm is oscillated by means of a pitman 26 or other suitable device. When the receptacle isl filled, the strip is'cut and the said receptacle which is provided with wheels 31 is moved upon the track 29 to a press 33 preferablyy a hydraulic press, although another style may be used if so desired. This press'which is heated, finishesk the block Without requiring a binding substance as the material, on account of always remaining in contact with .heated objects, is soft and flexible and binds construction, operation and many advantages'of the herein describedinvention will he a parent to those skilled in the art, Without urther description, and it Will be understood that various changes in the size, shape, proportion, and minoridetails of construction, may be resorted to Without departing from the s irit or sacrificing any of the advantages o the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by LettersPatent, is

l. A process for manufacturing blocks of linoleuin material or the like, consisting in making a plurality of strips from linoleum material of various colors, then uniting said strips to form a single strip, then folding said strip on itself in layers, andinally pressing the said layers to form a block.

2. A process for manufacturing blocks of linoleum material or the like consisting in dividing the said material into portions of l different color, then rolling said portions into 5 sai strips to form a single strip made up of l different colors, then folding saidfstrip into i stricps of corresponding color, then uniting layers, land finally pressing said layers to form a block.

3. A process for manufacturing blocks of linoleum material or the like, consisting in dividing the said material into portions of diiierent color, then rolling said portions into strifs of corresponding color, then uniting sai strips to form a single strip made up of dierent colors, then folding said stri into layers, in a heated receptacle, and ally pressing in a heated press said layers to form a block.

4. A process for manufacturing blocks of linoleum material or the like consisting in making a lurality of stri s from linoleum material, tlien uniting sai strips to form a single strip, then folding said strip into layers in a heated receptacle, and finally pressing in a heated press said layers to form a block.

In testimony, that I claim the foregoing as my own, I have hereto afiiXed my signature in the presence of two Witnesses.
